Mineral sunscreen composition
Abstract
A sunscreen composition includes a metal oxide sunscreen active, an emollient including a benzoate ester and an organosilicon compound, an emulsifier, and one or more other ingredients such as water. The metal oxide may be present in an amount between about 3.0 wt. % to about 20.0 wt. %, the benzoate ester may be present in an amount between about 5.0 wt. % to about 30.0 wt. %, the organosilicon compound may be present in an amount of about 3.5 wt. %, the emulsifier may be present in an amount between about 2.0 wt. % to about 10.0 wt. %, and water may be present in an amount of 30.0 wt. % or more, based on the total weight of the sunscreen composition. The sunscreen composition may be in the form of lotion that does not foam and is rubbed in to contact the keratinous surface.
